Mevo supports streaming to Facebook Pages.
If you wish to stream to a Page, you must be an Administrator. Moderators, Editors, and other roles cannot go live to Pages or Groups.
Once you are logged in to your account, tap the red button to start a stream and select Facebook. Your profile will be listed first, followed by Pages of which you are an admin.
Tap the desired destination to select it. Configure the rest of your settings as described here to go live.
